IDENTIFICATION ACT--Table of Contents
Sec. 303.7 Generic names and definitions for manufactured fibers.
Pursuant to the provisions of section 7(c) of the Act, the
Commission hereby establishes the generic names for manufactured fibers,
together with their respective definitions, set forth in this section,
and the generic names for manufactured fibers, together with their
respective definitions, set forth in International Organization for
Standardization ISO 2076: 1999(E), ``Textiles--Man-made fibres--Generic
names.'' This incorporation by reference was approved by the Director of
the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part
51. Copies may be obtained from the American National Standards
Institute, 11 West 42nd St., 13th floor, New York, NY 10036. Copies may
be inspected at the Federal Trade Commission, Room 130, 600 Pennsylvania
Avenue, NW., Washington, DC 20580, or at the National Archives and
Records Administration (NARA). For information on the availability of

(a) Acrylic. A manufactured fiber in which the fiber-forming
substance is any long chain synthetic polymer composed of at least 85
percent by weight of acrylonitrile units
[GRAPHIC] [TIFF OMITTED] TC29SE91.004
(b) Modacrylic. A manufactured fiber in which the fiber-forming
substance is any long chain synthetic polymer composed of less than 85
percent but at least 35 percent by weight of acrylonitrile units
[GRAPHIC] [TIFF OMITTED] TC29SE91.005
except fibers qualifying under paragraph (j)(2) of this section and
fibers qualifying under paragraph (q) of this section. (Sec. 7, 72 Stat.
1717; 15 U.S.C. section 70e)
(c) Polyester. A manufactured fiber in which the fiber-forming
substance is any long chain synthetic polymer composed of at least 85%
by weight of an ester of a substituted aromatic carboxylic acid,
including but not restricted to substituted terephthalate units,
[GRAPHIC] [TIFF OMITTED] TC29SE91.006
and para substituted hydroxy-benzoate units,
[GRAPHIC] [TIFF OMITTED] TC29SE91.007
Where the fiber is formed by the interaction of two or more chemically
distinct polymers (of which none exceeds 85% by weight), and contains
ester groups as the dominant functional unit (at least 85% by weight of
the total polymer content of the fiber), and which, if stretched at
least 100%, durably and rapidly reverts substantially to its unstretched
length when the tension is removed, the term elasterell-p may be used as
a generic description of the fiber.
(d) Rayon--A manufactured fiber composed of regenerated cellulose,
as well as manufactured fibers composed
[[Page 224]]
of regenerated cellulose in which substituents have replaced not more
than 15% of the hydrogens of the hydroxyl groups. Where the fiber is
composed of cellulose precipitated from an organic solution in which no
substitution of the hydroxyl groups takes place and no chemical
intermediates are formed, the term lyocell may be used as a generic
description of the fiber.
(e) Acetate. A manufactured fiber in which the fiber-forming
substance is cellulose acetate. Where not less than 92 percent of the
hydroxyl groups are acetylated, the term triacetate may be used as a
generic description of the fiber.
(f) Saran. A manufactured fiber in which the fiber-forming substance
is any long chain synthetic polymer composed of at least 80 percent by
weight of vinylidene chloride units (-CH9-CCl2-).
(g) Azlon. A manufactured fiber in which the fiber-forming substance
is composed of any regenerated naturally occurring proteins.
(h) Nytril. A manufactured fiber containing at least 85 percent of a
long chain polymer of vinylidene dinitrile (-CH2-
C(CN)2-) where the vinylidene dinitrile content is no less
than every other unit in the polymer chain.
(i) Nylon. A manufactured fiber in which the fiber-forming substance
is a long-chain synthetic polyamide in which less than 85 percent of the
amide
[GRAPHIC] [TIFF OMITTED] TC29SE91.008
linkages are attached directly to two aromatic rings.
(j) Rubber. A manufactured fiber in which the fiber-forming
substance is comprised of natural or synthetic rubber, including the
following categories:
(1) A manufactured fiber in which the fiber-forming substance is a
hydrocarbon such as natural rubber, polyisoprene, polybutadiene,
copolymers of dienes and hydrocarbons, or amorphous (noncrystalline)
polyolefins.
(2) A manufactured fiber in which the fiber-forming substance is a
copolymer of acrylonitrile and a diene (such as butadiene) composed of
not more than 50 percent but at least 10 percent by weight of
acrylonitrile units
[GRAPHIC] [TIFF OMITTED] TC29SE91.009
The term lastrile may be used as a generic description for fibers
falling within this category.
(3) A manufactured fiber in which the fiber-forming substance is a
polychloroprene or a copolymer of chloroprene in which at least 35
percent by weight of the fiber-forming substance is composed of
chloroprene units

(k) Spandex. A manufactured fiber in which the fiber-forming
substance is a long chain synthetic polymer comprised of at least 85
percent of a segmented polyurethane.
(l) Vinal. A manufactured fiber in which the fiber-forming substance
is any long chain synthetic polymer composed of at least 50 percent by
weight of vinyl alcohol units (-CH2-CHOH-), and in which the

percent by weight of ethylene, propylene, or other olefin units, except
amorphous (noncrystalline) polyolefins qualifying under paragraph (j)(1)
of this section [Rule 7]. Where the fiber-forming substance is a cross-
linked synthetic polymer, with low but significant crystallinity,

other olefin unit, and the fiber is substantially elastic and heat
resistant, the term lastol may be used as a generic description of the
fiber.
